By CNN’s math, that adds up to 228 passengers, one more than the total cited by the airline. There was no immediate explanation offered.

“Malaysia Airlines is currently working with the authorities who have activated their Search and Rescue team to locate the aircraft,” the statement said. The public can call +603 7884 1234 for further information.
